Web browser download of bookmark set

ABSTRACT

Bookmark sets are provided to a browser in a computer system by downloading a respective bookmark set as a unit. The process begins by creating a bookmark set at a first computer system computer system coupled to a network, the bookmark set containing a set of Uniform Resource Locators (URLs) and downloadable as a unit one or more computer systems. A request for downloading the bookmark set results in sending the bookmark set via the network to a second computer system. The bookmark set is received and used at the second computer system by a browser to access the set of URLs. The request for downloading the bookmark set can be initiated at the first computer system as a push operation or at the second computer system in a pull operation. The bookmark set can be set for automatic update; if changes are made at the first computer system, the updated bookmark set to the second computer system. The bookmark set can be incorporated in a downloaded web document. The browser parses for a tag in the web document which indicates the presence of a bookmark set in the web document and prompts for whether the incorporated bookmark set is to made available for use by the browser.

BACKGROUND OF THE INVENTION

This invention relates generally to information retrieval in a computernetwork. More particularly, it relates to an improved method forproviding a set of bookmarks in a browser for retrieving Web pages in anInternet environment.

It is well known to couple a plurality of computer systems into anetwork of computer systems. In this way, the collective resourcesavailable within the network may be shared among users, thus allowingeach connected user to enjoy resources which would not be economicallyfeasible to provide to each user individually. With the growth of theInternet, sharing of computer resources has been brought to a much wideraudience. The Internet has become a cultural medium in today's societyfor both information and entertainment. Government agencies employInternet sites for a variety of informational purposes. For manycompanies, one or more Internet sites are an integral part of theirbusiness; these sites are frequently mentioned in the companies'television, radio and print advertising.

The World Wide Web, or simply “the Web”, is the Internet's multimediainformation retrieval system. It is the most commonly used method oftransferring data in the Internet environment. Other methods exist suchas the File Transfer Protocol (FTP) and Gopher, but have not achievedthe popularity of the Web. Client machines accomplish transactions toWeb servers using the Hypertext Transfer Protocol (HTTP), which is aknown application protocol providing users access to files, e.g., text,graphics, images, sound, video, using a standard page descriptionlanguage known as the Hypertext Markup Language (HTML). HTML providesbasic document formatting and allows the developer to specify “links” toother servers and files. In the Internet paradigm, a network path to aserver is identified by a Uniform Resource Locator (URL) having aspecial syntax for defining a network connection.

Retrieval of information is generally achieved by the use of anHTML-compatible “browser”, e.g., Netscape Navigator, at a clientmachine. When the user of the browser specifies a link via a URL, theclient issues a request to a naming service to map a hostname in the URLto a particular network IP address at which the server is located. Thenaming service returns a list of one or more IP addresses that canrespond to the request. Using one of the IP addresses, the browserestablishes a connection to a server. If the server is available, itreturns a document or other object formatted according to HTML. Webbrowsers have become the primary interface for access to many networkand server services.

The entry of the URL in the entry field of a browser can be a difficulttask for many users. While the URL for the main Web page of a majorcompany can be relatively brief, e.g., www.ibm.com, subsidiary pages canhave very lengthy URLs in, at least to the average user, an arcanesyntax. Recognizing the difficulties involved, the developers ofbrowsers have provided one useful means of returning to a favorite URL,by the creation of user stored “bookmarks” in the browser.

Web browsers offer many options in the user interface for creating abookmark list. Basic options let the user add and access a page througha pop-up menu on the location toolbar or through a menu pulldown fromthe main menu bar. A simple way to add a bookmark for a favorite page isto enter the URL to travel to the page, once there, open the Bookmarksmenu and choose the Add Bookmarks selection. This set of actions addsthe URL of the current page as an item in the Bookmarks menu.

Once created, bookmarks offer a means of page retrieval. The user cancause the browser to display his bookmark list and select among hisbookmarks to go directly to a favorite page. Thus, the user is notforced to enter a lengthy URL nor retrace the original tortuous routethrough the Internet by which he may have arrived at the Web site. Oncea bookmark is added to a bookmark list, in general, the bookmark becomesa permanent part of the browser until removed. The permanence andaccessibility of bookmarks have made them a valuable means forpersonalizing a user's Internet access through the browser.

Yet despite their usefulness, the current arrangement of bookmarks isnot without its flaws. As the numbers of web sites and web pages onthese sites have increased dramatically, so has the number of bookmarksthat a typical web browser user maintains on his browser. It is notuncommon that hundreds of bookmarks be stored in a bookmark file after afew weeks of web browsing. While folders in some browsers have helpedthe user group his bookmarks by category, in reality, the bookmark fileis one huge list of bookmarks, all accessible to the user through thebrowser. This present invention is concerned with providing structureand additional function to this amorphous entity, the bookmark file.

One problem not addressed by the current bookmark schemes is accesscontrol. In the current browser environment, all bookmarks areaccessible to the user at all times. There are certain environments,e.g., a work environment or a home environment with young children, inwhich this power is not an unmixed blessing.

The most common way of adding bookmarks to the bookmark file in thebrowser is manually intensive. Each bookmark is added one at a time. Auser visits a web site, then selects that site as a bookmark entry and,if desired, categorizes it manually. Furthermore, the current technologyused in browsers to update bookmarks, i.e. removing the old address andentering the new one, is very slow and inefficient.

Bookmarks are currently used merely as an aid for navigation on a siteby site basis. Once at a web site, the bookmark list is unused innavigation until a new web site in the user's bookmark list is desired.Bookmarks lend a uniform navigation means to an otherwise unordered Web;it is unfortunate that their utility has been untapped for intrasitenavigation.

These problems as well as others are addressed in various embodiments ofthe present invention.

SUMMARY OF THE INVENTION

Therefore, it is an object of the invention to improve the management ofbookmarks in the browser.

It is another object of the invention to provide bookmarks sets from aweb page selectable by a browser.

It is another object of the invention to automatically update a browserbookmark list of a subsequent visit to a bookmarked web site.

These and other objects are accomplished by providing bookmark sets to abrowser in a computer system by downloading a respective bookmark set asa unit. The process begins by creating a bookmark set at a firstcomputer system computer system coupled to a network, the bookmark setcontaining a set of Uniform Resource Locators (URLs) and downloadable asa unit one or more computer systems. A request for downloading thebookmark set results in sending the bookmark set via the network to asecond computer system. The bookmark set is received and used at thesecond computer system by a browser to access the set of URLs. Therequest for downloading the bookmark set can be initiated at the firstcomputer system as a push operation or at the second computer system ina pull operation. The bookmark set can be set for automatic update; ifchanges are made at the first computer system, the updated bookmark setto the second computer system. The bookmark set can be incorporated in adownloaded web document. The browser parses for a tag in the webdocument which indicates the presence of a bookmark set in the webdocument and prompts for whether the incorporated bookmark set is tomade available for use by the browser.

DETAILED DESCRIPTION OF THE DRAWINGS

The invention may be run on a variety of computers or collection ofcomputers under a number of different operating systems. The computercould be, for example, a personal computer, a mini computer, mainframecomputer or a computer running in a distributed network of othercomputers. Although the specific choice of computer is limited only byprocessor speed and disk storage requirements, computers in the IBM PCseries of computers could be used in the present invention. Oneoperating system which an IBM personal computer may run is IBM's OS/2Warp 4.0. In the alternative, the computer system might be in the IBMRISC System/6000 (TM) line of computers which run on the AIX (TM)operating system.

In FIG. 1, a computer 10, comprising a system unit 11, a keyboard 12, amouse 13 and a display 14 are depicted in block diagram form. The systemunit 11 includes a system bus or plurality of system buses 21 to whichvarious components are coupled and by which communication between thevarious components is accomplished. The microprocessor 22 is connectedto the system bus 21 and is supported by read only memory (ROM) 23 andrandom access memory (RAM) 24 also connected to system bus 21. Amicroprocessor in the IBM PC series of computers is one of the Intelfamily of microprocessors including the 386, 486 or Pentiummicroprocessors. However, other microprocessors including, but notlimited to, Motorola's family of microprocessors such as the 68000,68020 or the 68030 microprocessors and various Reduced Instruction SetComputer (RISC) microprocessors such as the PowerPC chip manufactured byIBM. Other RISC chips made by Hewlett Packard, Sun, Motorola and othersmay be used in the specific computer.

The ROM 23 contains among other code the Basic Input-Output system(BIOS) which controls basic hardware operations such as the interactionof the processor and the disk drives and the keyboard. The RAM 24 is themain memory into which the operating system and application programs areloaded. The memory management chip 25 is connected to the system bus 21and controls direct memory access operations including, passing databetween the RAM 24 and hard disk drive 26 and floppy disk drive 27. TheCD ROM 32 also coupled to the system bus 21 is used to store a largeamount of data, e.g., a multimedia program or presentation.

Also connected to this system bus 21 are various I/O controllers: Thekeyboard controller 28, the mouse controller 29, the video controller30, and the audio controller 31. As might be expected, the keyboardcontroller 28 provides the hardware interface for the keyboard 12, themouse controller 29 provides the hardware interface for mouse 13, thevideo controller 30 is the hardware interface for the display 14, andthe audio controller 31 is the hardware interface for the speakers 15.An I/O controller 40 such as a Token Ring Adapter enables communicationover a network 46 to other similarly configured data processing systems.

One of the preferred implementations of the invention is as sets ofinstructions 48-52 resident in the random access memory 24 of one ormore computer systems configured generally as described above. Untilrequired by the computer system, the set of instructions may be storedin another computer readable memory, for example, in the hard disk drive26, or in a removable memory such as an optical disk for eventual use inthe CD-ROM 32 or in a floppy disk for eventual use in the floppy diskdrive 27. Further, the set of instructions can be stored in the memoryof another computer and transmitted over a local area network or a widearea network such as the Internet when desired by the user. One skilledin the art would appreciate that the physical storage of the sets ofinstructions physically changes the medium upon which it is storedelectrically, magnetically, or chemically so that the medium carriescomputer readable information. While it is convenient to describe theinvention in terms of instructions, symbols, characters, or the like,the reader should remember that all of these and similar terms should beassociated with the appropriate physical elements.

Further, the invention is often described in terms that could beassociated with a human operator. While the operations performed may bein response to user input, no action by a human operator is desirable inany of the operations described herein which form part of the presentinvention; the operations are machine operations processing electricalsignals to generate other electrical signals.

A web browser is a program that allows viewing the content of theInternet. A well known web browser is Netscape Navigator, however, manybrowsers exist. Some are general purpose and have many capabilities toprovide a variety of functions. Other are less capable and specialpurpose. In general, a web browser is a program which is capable ofparsing and presenting a document written in HTML, although thoseskilled in the art would appreciate that other markup languages such asdynamic HTML and XML will be used in the browsers of the future. In thepresent invention, the browser must also be equipped with a bookmarkmanager, a software module which handles sets of bookmarks which providereferents, typically URLs, to various locations in the Internet. Thebookmark manager is preferably part of the browser itself.

Upon starting a web browser, the first page the user sees is the current“home page”. The URL of the home page can be regarded as the firstbookmark in the browser. Although entry of a URL is one way of browsingthe Web, the user may also traverse to another Web page by clickinghighlighted words, images or graphics in a page activating an associatedhyperlink to bring another page of related information to the screen.Each hyperlink contains URL location information that serves as anaddress of the web site. Navigational aids such as Back and Forwardtoolbar buttons are available to proceed back or forward to pages whichhave been previously accessed. Other navigation aids are the bookmarkswhich are used in the present invention.

In the Internet, the Web server accepts a client request and returns aresponse back to the client. A series of server computers may beinvolved in the retrieval of a specific web page. The operation of theserver program is governed by a number of server application functions(SAFs), each of which is configured to execute in a certain stop of asequence. This sequence, illustrated in FIG. 2, begins with theauthorization translation step 75 during which the web server translatesany authorization information sent by the web client into a user and agroup. If necessary, the step 75 may decode a message to get the actualclient request. At the name translation step 77, the URL associated withthe request may or may not be translated into a system-dependent filename, a redirection URL or a mirror site. In the path checks step 79,the server performs various tests on the resulting path to ensure thatthe given client may retrieve the document.

In step 81, Multipurpose Internet Mail Extension (MIME) typeinformation, e.g., text/html, image/gif, for the given document isrecognized. In the service step 83, the Web server routine selects aninternal server function to send the retrieved information back to therequesting web client. This function can run the normal server serviceroutine to return a file or some other server function, such as aprogram to return to return a custom document or a CGI program. At theAdd Log step 85, information about the transaction is recorded.

A URL or “Uniform Resource Locator” is defined in RFC 1945, which isincorporated herein by reference. As is well known, the URL is typicallyof the format: http://somehost/somedirectory?parameters . . . ” where“somehost” is the hostname position of the URL, “somedirectory” is adirectory in which the web page may be found. The usual manner in whicha URL is resolved into an actual IP address for a web server is throughthe use of a nameserver. In an internet or intranet network, anameserver maps hostnames in URLs to actual network addresses. Anexample of a nameserver is the Domain Name Service (DNS) currentlyimplemented in the Internet. The process of having a Web client requesta hostname and address from a nameserver is sometimes called resolution.In TCP/IP, the nameserver resolves the hostname into a list of one ormore IP addresses which are returned to the Web client on an HTTPrequest. Each IP address identifies a server which hosts the requestedcontent made by the browser.

Each bookmark entry is comprised of a URL to a favorite page and anassociated descriptive text string which describes the web page in sucha way to be easily recognized by the user. The descriptive text can beentered by the user when creating the bookmark set. Also, the typicalbrowser default, when the user does not enter any descriptive text, isto use the text within an embedded “title” tag which is often sent aspart of the HTML header. Other information such as pointers to cachedcopies of the web page can be included in the bookmark entry.

Named Internet Bookmark Sets

Current web browsers process bookmarks as single URL entities within asingle repository of bookmarks. Some browsers have the capability toorganize the bookmarks by folders; however, even if a particular folderis chosen, all bookmarks remain available for selection withoutrestrictions. While the user can group the bookmarks into severaluser-specified categories, an entity which operates like the “bookmarkset” described by the Applicants is lacking. The inability of prior artbrowsers to process groups of bookmarks, particularly subgroups of theoverall bookmark list, as an entity is disadvantageous.

For example, it is possible to include a list of bookmarks in anelectronic message to another user. However, this takes a lot of manualwork by one user to make the list and more work by a second user toincorporate the list into the second user's browser's bookmark list. Itis not possible to request a downloadable bookmark set which is smoothlyintegrated in the bookmark file of prior art browsers in a singleoperation.

As another example, in prior art browsers, bookmarks can not beinstalled as a set, nor once installed can bookmarks be managed, e.g.,stored, selected or deleted, as a bookmark set. When installing bookmarkentries, prior art web browsers require the users to install eachbookmark individually rather than installating a group of bookmarks as aset. Prior art web browsers do not support the concept of deleting abookmark set, where all the bookmark entries are deleted as a set. Themaintenance of bookmark entries in the prior art web browsers requiresmanual intervention, handling individual URLs for all bookmark entries.

This invention creates the concept of “bookmark sets” to provide greatercapability than exists in the prior art bookmark technology.

A bookmark set is an entity which has attributes of its own, e.g.,active vs. inactive, and manages attributes and behavior, e.g., dynamicvs. static, of its individual bookmarks. A bookmark set is a finitecollection of bookmarks that have static and dynamic characteristics. Anaction such as selection, deletion or e-mail transmission can beaccomplished for the entire set in a single operation by the user.

Since the bookmark list in prior art web browsers is basically one hugelist, they allow unrestricted access to all bookmark entries, regardlessof classification. The present invention adds the concept of an “active”bookmark set. Each bookmark set is a collection of bookmark entries thatcan be made active or inactive as a working set. The active bookmark setcomprises the only bookmarks which can be accessed through the bookmarkmechanism.

In some embodiments below, the active bookmark set is the only list ofweb sites, including their subdirectories, that can be visited by use ofthe browser. In these embodiments, the main “user” is the programdeveloper, the system administrator or parent, who allows lessprivileged users limited access to the Internet. Those web sites outsidethe active set require special password permission to access. In theseembodiments, a bookmark set is not only a collection of URLs, butprecludes an unprivileged user from unlimited browsing or adding moreURLs to the bookmark set. This is not possible in current browsers inwhich the bookmark function can not be configured to limit the bookmarklist to a specific URL set.

Bookmark sets allow the user to create specific sets of URLs dependingon his or her needs. For example, a privileged user can configure anOffice bookmark set, a Home bookmark set and a Daughter bookmark set tosatisfy each of the environments and users of the browser. Some or allof the bookmark sets may be password protected to use. In someembodiments, there is an additional password to modify or create abookmark set. A sample “work” bookmark set is given below:

Work:

www.HTML.Reference/Definitions”//Descriptors/index.html

www.Javasoft.Javadefinition.com

w3.myproject/FVN.results.com

w3.status report.project office/myproject.status

w3.server.performance/my project.results

w3.myproject/resources1/people

The text descriptors are the “Title Page” that comes in the HTTP header.

The invention allows the association of a home page with each respectivebookmark set. Thus, when the user switches the active bookmark set fromhis Home bookmark set to his Work bookmark set, his home page switchesas well. An alternative embodiment is to have a home page bookmark set.Each successive activation of the home page button of the browser wouldopen a different home page window until all of the configured home pageswere retrieved.

As described above, the invention allows the user to create specific andunique bookmark sets for each of the tasks for which he uses thebrowser. Although the bookmark set could be designated active in manyways, a bookmark set can be activated through a browser configurationoption. For example, by a “Select active bookmark set” option in abookmark pulldown, the user can specify the unique bookmark set that isactive at any one session.

For example, on a portable computer which is used both at home and work,a user can have a “work” bookmark set, a “hobbies” bookmark set, a“news” bookmark set, a “kids” bookmark set and a “financial” bookmarkset using this invention. The members of the household who use thecomputer can possess the appropriate passwords to the appropriatebookmark sets. They make their bookmark sets active through the use ofthe bookmark pulldown.

The user at work can select his “work” bookmark set as his activebookmark set. All other bookmark sets are inactive and can only beactivated through the browser preferences menu. For the privileged user,the ability to manage bookmark sets as a collection of bookmarks insteadof managing one URL at a time like in the folder paradigm isadvantageous. For example, the ability to change an attribute of all thebookmarks, e.g., inactive, active, dynamic, static, or to perform anaction such as deletion or password protection for all the bookmarks inthe active set is part of the invention. Also, the privileged user mayexercise control over the web sites to which non-priviledged users haveaccess.

An illustrative method of creating a bookmark set according to theinvention is shown in FIG. 3. Those skilled in the art will recognizethat other steps in other user interfaces may be used to assemble abookmark set. In step 101, the bookmark manager is activated in responseto user selection of the bookmark item on the browser pulldown menu. Instep 103, after the menu item “Create named bookmark sets” is selectedthrough a browser preferences menu in the browser, a creation routinefor the bookmark set is initiated. In step 105, the user is prompted fora password. Step 107 tests whether the password was enteredsuccessfully. If not entered successfully within the number of attemptsallowed by the browser security protocol, the process ends, step 109. Atthis point, other actions such as browser lockup, disconnect from thenetwork as well as various alarms are possible.

Presuming the user successfully enters a password, in step 111, a newbookmark file is allocated for the new bookmark set. In the preferredembodiment, a bookmark set definition is contained within a singlebookmark file. At the time of the creation of the bookmark set, the useris prompted for a name for the set, step 113. Next, the user can specifya URL, i.e. bookmark, that belongs to the set, step 115. A textdescriptor for each bookmark is also added in this step. The systemtests each bookmark and that a bookmark set name and at least one URL isadded to the bookmark set, step 117. If not, the user is prompted thatthere is not enough information to create a bookmark list, step 119, andgiven an opportunity to provide the missing information. In step 121,the user is asked whether there is another bookmark to add to the set.If so, the process returns to step 115.

The user is queried whether the bookmark set is to be passwordprotected, in step 123. The user is prompted for the password whichbecomes part of the bookmark set, step 125. Step 127 represents thecreation of the bookmark set and the addition of its name into a menu ofselectable bookmark sets. Once created, the users with the appropriatepermissions can access the bookmark set.

The selection of the active bookmark set through the browser preferencesmenu is shown in FIG. 4. In step 151, the names of the selectablebookmark sets are displayed in tabular form by the browser. Thosepassword protected may be marked by some indicia, e.g., an icon orcoloration. In step 153, in response to user selection of a bookmark setto be active, the system retrieves password information for the bookmarkset, if any. If there is password protection, the user is prompted forthe password, step 155. If it is not correctly entered, step 156, afterthe allowed number of attempts, the process exits, step 157. Variouslockup actions as described above may take place if the user attempts toaccess a bookmark set for which he lacks the correct password.

If the password is correctly entered, in step 159, the selected bookmarkset becomes the active set. In step 161, the browser uses entries in theactive bookmark set to list the available bookmark URLs, typically asthe text strings which accompany the actual URLs. In step 163, thecurrent page is saved as a bookmark in response to a user action in theinterface, e.g., selection of “add to bookmark set” option. The saveaction for a bookmark for the page saves the bookmark to the activebookmark set. In this way, the bookmark manager can automatically addbookmarks to the active bookmark set without actually requiring the userto type out the URL and text descriptor, step 165. This action of addingURLs to the bookmark set can be protected by a separate password, ifdesired (not shown). In step 167, a test detects that the user hasindicated that he wants to modify a bookmark in the active bookmark set.A password may be required (not shown). If allowed to change thepassword, the system modifies the password in response to user input,step 168. The bookmark manager also detects whether the user wants todelete the entire bookmark set, step 169. If allowed, the bookmarkmanager deletes the active set in step 170 and returns to step 151 topresent the bookmark set list. The bookmark manager also detects whetherthe user wants to rename the bookmark set, step 171. If allowed, theactive bookmark set is renamed. Only bookmarks in the active set areavailable for modification, deletion or renaming in the preferredembodiment of the invention.

Other changes such as changing an attribute of the bookmark set or thetype of password protection for the bookmark set are not illustrated inthe figure. While any alteration of the bookmark set may be passwordprotected by an additional level of security, in one embodiment of theinvention, a user who has access to a bookmark set automatically has theright to modify it.

The use of active and inactive bookmark sets not only provides aconvenient grouping of URLs to organize the browser environment, but inone preferred embodiment, as a method to preclude the user from visitingWeb sites not included in the bookmark set. In this embodiment, onlywhen the bookmark set is active can the user access the URLs associatedwith the bookmark set. (In other embodiments, the restriction onlyapplies to access through the bookmark list pulldown menu, but notthrough other means.) As shown in FIG. 5, the browser checks whether aURL is in the active bookmark list before allowing the user to browse orretrieve web pages at the site.

In step 201, the user has selected a next URL to browse, either by entryin the URL field of the browser or by activating the hyperlink in abrowsed page. The reader should note that in some preferred embodimentsof the browser, there is no field in which to enter a URL so that theuser is more constrained to the bookmark set. In step 203, the browserchecks the selected URL against the list of URLs in the active bookmarkset. If a match for the URL is not found, or in a subdirectory of alisted URL, step 205, a panel is shown to the user indicating an errorhas occurred; e.g., “The requested web site can not be browsed with thecurrent active bookmark set”, step 206. A privileged user could changebookmark sets, step 207. In the alternative, a permitted URL can bechosen, back to step 201. Persistent attempts to reach unlisted URLscould result in a browser lockup or an alarm. If the URL is listed, instep 209, the browser retrieves the web page associated with the URL andproceeds normally.

Important implementions of the bookmark set include unique point of saleor other special purpose applications. In one implementation of thebookmark set, a user receives a CD-ROM in the mail or with a magazine.The CD-ROM contains a browser equipped with the bookmark manager and asingle active bookmark set. Thus, the browser can only access the URLaddresses that the vendor wants to advertise.

Also, the kiosk or point of sale environment is another potentialapplication for bookmark sets. In a kiosk, typically sponsored by avendor, the browser may only have access to specific addresses. Thisprevents the user from accessing unrelated URLs, wasting the vendor'sresources. The retailer which owns the kiosk can rent out the kiosk tointerested vendors. It is an easy matter to switch the active bookmarkset with a change of vendors.

FIGS. 6A and 6B respectively show the user interface of prior artbookmark technology and the user interface of the bookmark technology ofthe present invention. As shown in FIG. 6A, in the prior art interface,all of the bookmarks 251 stored in the browser are made available to theuser for selection. The only possible organization of the bookmark listis by folders or topics.

FIG. 6B shows a user interface of a browser using the bookmark settechnology. Notice that the user has only one active bookmark set 261 ata time. In the example, the user has three bookmark sets, Children 263,Home 261 and Office 265, and only the Home bookmark set 261 is availableusing the bookmarks pulldown menu. Referring to the bookmark setmanager, a user will see the current bookmarks associated with theactive bookmark set. To modify or access an inactive bookmark set, if heis allowed, the user first makes it the active bookmark set.

Internet Blacklist Bookmark Set

In this embodiment of the invention, a special type of bookmark set, theblacklist bookmark set, is introduced.

As noted above, prior art Web browsers allow unrestricted user access toany URL on the internet. A system administrator or parent that wants torestrict access to specific URLs or to a set of URLs requires an add-onprogram to the web browser that filters TCP/IP addresses. This methodlacks granularity, any desired URL at the same TCP/IP address isrestricted as well as the undesired ones. By using the TCP/IP address asthe determiner, both the acceptable and as well as the unacceptable URLsbecome inaccessible to the browser.

There is no control mechanism within the prior art browser itself. Asthe filtering application is outside the browser, the prior art browserstill makes the attempt to connect to a prohibited URL. This arrangementresults in unnecessary use of client system resources.

It would be much more useful to restrict access to unique URLs using thebrowser itself. While the embodiment above provides one means ofcontrolling access to the web to the list of active bookmarks, itscontrol is primarily a positive one. The user has access to all of theURLs reachable from a particular Web site. This is not a fine filteringarrangement.

Thus, the invention adds the blacklist bookmark set to allow a systemadministrator or any browser user to specify one or more URLs, as a setof URLs for which restricted access is desired. The blacklist bookmarkset contains a number of blacklisted URLs to which a web browser user isprohibited from accessing, no matter what bookmark set is active. Ineffect, the blacklist bookmark set is a second active bookmark set whichis always active and qualifies the access granted to the Internet by theother active bookmark set. The use of two bookmark sets can provide afine filtering mechanism with a minimum of URL entry.

As the reader will recall, some of the embodiments of the activebookmark set above use the active bookmark set only as a filter forbookmark access to URLs. If this is the case, the blacklist bookmark setwill be the only filter. In one embodiment of the blacklist bookmarkset, it is used alone without an active permissive bookmark set of theembodiment above.

In the preferred embodiment, the blacklist bookmark set is created andmodified through the browser preferences menu. The method of creating ablacklist bookmark set is similar to that described in connection withFIG. 3 above. However, at least the removal of blacklisted bookmarksshould be password protected. To add a bookmark to the blacklistbookmark set rather than the active bookmark set, the blacklist bookmarkoption in the browser preferences should be chosen.

The web browser user can access any URL in the current active bookmarkset, except those listed in the blacklist bookmark set. In one preferredembodiment, only the system administrator can add, remove or modifyblacklist bookmarks through the browser preferences menu. However, in analternative embodiment, the user can add the blacklist bookmarks, butcan not delete or modify blacklisted URLs. In the alternativeembodiment, the web browser administrator is the only person allowed toremove or modify blacklisted URLs from the blacklist bookmark set.

In the preferred embodiment, the web browser user is not allowed even toview the blacklist bookmark set. However, this is optional. In thispreferred embodiment, the system administrator is the only one capableof viewing the blacklist bookmark set and this action is protected viapassword.

The web browser user can not add an explicitly blacklisted URL to hisregular bookmark set. The bookmark manager will detect this act andnotify the user that it is not permitted. However, since some URLs atthe same site may be acceptable, the user can add URLs which are relatedto the blacklisted URL. When the user attempts to traverse to theblacklisted URL, e.g., by hyperlink, the bookmark set manager willdetect that the destination URL matches one in the blacklist anddisallow the action. If the system administrator updates the blacklistbookmarks set such that one of the entries matches an entry in one ofthe user's bookmark sets, preferably the matching entry will be removedfrom the user's bookmark set. In any event, the user will be precludedfrom visiting the old bookmarked site.

The blacklist bookmark set is a more effective and efficient means ofpreventing access to blacklisted URLs than the helper applications ofthe prior art. Since the blacklist bookmark set is an integral part ofthe browser, processor time is not wasted making HTTP requests todisallowed URLs. Since the blacklist is on a URL basis rather than on aTCP/IP address basis, finer granularity is achieved. Since the blacklistbookmark set is an entity, it can be easily installed as a unit in manybrowsers connected to the network. Thus, tedious entry of bookmarks isavoided. If the blacklist bookmark set is updated by the administrator,the new set can be similarly distributed to the users. Of course, it ispossible to distribute one blacklist bookmark set to one set of usersand another blacklist bookmark set to a second set of users. In theblacklist bookmark set, password attributes can be attached to theindividual manipulation actions for the blacklist bookmark set. Thus,when it is downloaded to the user, the bookmark set manager at thebrowser can maintain the policies desired by the administrator.

The manipulation of the blacklist bookmark set is shown in FIG. 7. Instep 271, the blacklist bookmark set is selected in the browserpreference menu. In step 272, the browser has detected that the user hasselected the view bookmark set option. In step 273, the bookmark setmanager ascertains whether this action is password protected. If so,step 274 prompts for the password. In step 275, a test determineswhether the password was entered correctly. If not password protected,or the password is authentic, the blacklist bookmark set is presented,step 276. Otherwise, in step 277, an error panel is shown to the user.

In step 278, the browser has detected user selection of the add bookmarkoption. In step 279, the bookmark set manager determines whether thisaction is password protected. If so, step 280 prompts for the password.In step 281, a test determines whether the password was enteredcorrectly. If not password protected, or the password is enteredcorrectly, a panel to add the bookmark to the blacklist bookmark set ispresented in step 282. The bookmark is added in step 283. Otherwise, instep 284, an error panel is presented to the user.

In step 285, the browser has detected user selection of the removebookmark menu item. In the preferred embodiment, this action is passwordprotected. Step 286 presents a panel for the password. In step 287, thebookmark set manager determines whether the password was enteredcorrectly. If the password is correct, a prompt to select a bookmark tothe blacklist bookmark set is presented in step 288. The bookmark isdeleted in step 289. In step 290, an error panel is presented to theuser who enters the password incorrectly.

In step 291, the browser has recognized user selection of the modifybookmark option. In the preferred embodiment, this action is passwordprotected. Step 292 prompts for the password. In step 293, the bookmarkset manager decides whether the password was entered correctly. If thepassword is entered correctly, a prompt to select a bookmark to theblacklist bookmark set is presented in step 294. The bookmark ismodified in step 295 according to user input. In step 296, an errorpanel is shown to the user who enters the password incorrectly.

FIG. 8 shows a flowchart of the blacklist bookmark set process. In step301, the blacklist bookmark set is created, retrieved from the server orotherwise provided to the local browser and added to the residentbookmark sets. In step 303, the browser detects the entry of adestination URL either through hyperlink or through manual entry. Instep 305, the browser detects whether it matches an entry in the activebookmark set. If not, the browser denies the user access, step 307, anddoes not fetch the URL. If so, in step 309, the browser tests whetherthe URL matches a blacklisted URL in the blacklist bookmark set. If so,in step 311, the browser denies the user's request and does not retrievethe web page. If not, in step 313, the browser accesses the web site asnormal.

The blacklist bookmark set is useful in a variety of applications. Apoint of sale kiosk can be equipped with a browser with a blacklistbookmark set. Many smaller companies do not wish to assume themaintenance costs or technical skills associated with maintaining a webpage on a web server. These companies will hire an Internet specialistcompany to provide the web server and skilled technicians. Manycompanies may be on the same server at the same IP address. A companywho rents the kiosk from the retailer may not wish the users to accessother pages at the same TCP/IP address. The helper applications of theprior art could not achieve this granularity.

A corporate intranet is another application of the present invention. Anetwork administrator can quickly install and maintain updated versionsof a blacklist bookmark set to assure appropriate use of companyresources. By placing the control in the browser itself, additionalexpenditures for an add on application at each client system isunnecessary. Stopping inappropriate requests at a proxy server is alsopossible, however, the invention eliminates network traffic associatedwith the disallowed requests and server responses to those requests.

Although the preferred embodiment of the invention uses the blacklistbookmark set in conjunction with an active bookmark set, selected activefrom a number of bookmark sets as described above, it is possible thatthe blacklist bookmark set can be used alone. That is, the blacklistbookmark set can be used in a browser that does not otherwise understandthe notion of bookmark sets.

While individual entry of bookmarks can result in a blacklist bookmarkset with many entries, it depends how granular and restrictive theadministrator or parent wishes to be. Furthermore, wild carding ofblacklisted URLs using the server name and subdirectory can avoid manualentry of many bookmarks. For example, where “*” is a wild card in thebookmark syntax, a blacklist entry of www.yahoo.com/((example please))/*will prevent access to any web pages in that directory but allow theuser to access the many appropriate web pages available at the yahoosite.

Web Browser Download of Bookmark Set

As the number of web sites has increased dramatically in the past coupleof years, so has the number of bookmarks that a typical web browser usermaintains on his browser. It is not uncommon now to include hundreds ofbookmarks in a bookmark file just after a few weeks of web browsing. Themost common way of adding bookmarks to the bookmark file in the priorart browser is to visit a web site, then select that site as a bookmarkentry and, if desired, categorize it manually. However, these bookmarksstill need to be entered one at a time. The prior art technology used inbrowsers to update bookmarks is very slow and inefficient. Thus, thecreation and maintenance of bookmarks has become a chore for the user.

As can be seen above, the introduction of the notion of the bookmark setentity can provide a number of features unavailable in prior artbrowsers. The bookmark set also facilitates the creation, installationand maintenance of bookmarks by downloading them in bookmark sets fromdesired web servers. The web server could be a server associated with acompany intranet or other corporate server. Such a server mightsimultaneously update a plurality of bookmark sets at a plurality ofclient stations. Alternatively, the web server might be associated witha public web site accessible to any number of users. The downloadprocess for bookmark sets can be a pull or a push type operation. From auser interface standpoint, it is a single step process to updatebookmarks in an easy, automatic and painless way.

As is discussed below, web sites can provide a user friendly method toadd multiple URL addresses to a browser as a bookmark set via a singleselection. Web masters can create a site bookmark set for clientsinterested in the site URLs. In one preferred embodiment, the web mastercan use special tags or MIME types to identify the nature of the file tobe transferred. The bookmark set manager in the browser uses these tagsor MIME types to add the bookmark set to the browser's collection ofbookmarks.

The user can request a bookmark set by selecting a bookmark set link inthe site pages. Alternatively, the user can request the browser for thebookmark set by actuating a button in the browser user interface. Thebookmark set request will trigger a download request to the server fromthe client machine. The browser at the client receives this bookmark setand stores the URLs in its bookmark sets. In one preferred embodiment,the bookmark manager makes the new set the active bookmark set and thusrendering them available for browser use immediately.

For example, this invention will allow a user browsing the IBM home pageto download the IBM bookmark set containing URL references to Aptivapersonal computers, ThinkPad portable computers, Server computers,Software and so forth.

In one preferred embodiment, the web site server can also automaticallynotify the user if the bookmark set has been updated and suggest thatthe user get a new copy of the bookmark set for the site. The user canhave a option to subscribe to the bookmark set for updates. In this way,the downloaded bookmark set becomes dynamic in nature. Dynamic update ofindividual bookmarks within a bookmark set is discussed in greaterdetail below.

A first embodiment of the invention is a pull operation initiated by theuser at a client web browser as shown in FIG. 9. This figure shows auser interface of a web site with a button 351 for requesting a sitebookmark list be downloaded to the client. Several such buttons could bepresent. For example, on an “index” web site, e.g.,www.yahoo.collection.com, which makes an effort to provide comprehensivelists of related web sites, a plurality of buttons are possible, eachfor a different bookmark set. Once activated, a dialog box 352 ispresented, asking the user if it is to be a temporary or permanentbookmark set. If a permanent bookmark set is chosen, another dialog box353 is presented, asking the user if he wants to subscribe to thebookmark list for updates. The dialog box setting the bookmark setattribute is presented by the bookmark set manager in the browser. Thesubscription option is presented preferrably by the web page.

FIG. 10 is a flow diagram showing the pull process between networkcomponents in a bookmark set download. The process begins in step 401with an HTTP request from the browser to a web server with a bookmarkset. In step 403, the browser has retrieved a home page for a web sitewhich specifies a set of URLs that can be downloaded to a web browser asa unit, a bookmark set. Within the home page, there is an HTML tag that,when parsed and/or otherwise detected by the browser, step 404, liststhe available bookmark sets that can be incorporated in the browser.Through the user interface, the user may select to install one or morebookmark sets made available by the site. The bookmark set couldalternatively be incorporated in an HTML file other than a web page. Inany case, the bookmark sets will generally point to web referencespertaining a subject related to the theme of the visited site.

In the HTML tag, the bookmark set is specified through a unique MIMEtype, e.g., x-bookmark-set, that if selected by the user gets added tothe browser's bookmark options. For example, the HTML for adding abookmark set for a computer manufacturer would look like:

Content_type: text/Bookmark set <line feed> <line feed>

<HTML>

<HEAD><TITLE> GM Bookmark sets </TITLE> </HEAD>

. . . . .

</HTML>

In step 405, the browser has detected user input indicating that theuser wants to install a downloaded bookmark set. The user input could beactivation of a button or other selection means presented in the webpage. Alternatively, the browser preferences in the bookmark managercould be set to download the bookmark set, either as a default action tooccur whenever a page with a bookmark set is encountered or because thebookmark set was previously downloaded. In step 407, the browserpresents the user with two options to install the downloaded bookmarkset: Install as a temporary bookmark set; or Install as a permanentbookmark set. A temporary bookmark set only lasts for the currentbrowsing session. A permanent bookmark set become a permanent part ofthe browser until deleted. In one preferred embodiment, permanentbookmark sets are dynamically updated. One skilled in the art wouldappreciate that other options are possible.

In step 409, the browser checks to see if a similarly named bookmark setis already stored. If so, in step 411, the action to download a bookmarkset with the same name as an already installed bookmark set will causethe browser to pop up a dialog box requesting permission to write overthe old set. If permission is granted, the old bookmark set is deletedin step 412 and the newly downloaded bookmark set is installed in step413. It is made the active set in step 415 so that it can be immediatelyused.

When the user indicates that he no longer wants the bookmark set, e.g.,by input to the user interface, step 419, the bookmark manager willsimply delete the bookmark entries with the bookmark set, step 421. Fromthe user perspective, all the bookmark entries contained in the set aredeleted in a single operation. In the case of a temporary bookmark set,no user action is necessarily required. Setting the attributes of abookmark set as temporary can be done by the user when it is downloadedor it may already have temporary attributes from the web server itself.

The concept of downloading bookmark sets relies on a web designercreating one or more bookmark sets for the site they are designing.Today, some Web sites use the concept of “site maps” to get visitorsfamiliar with the site. However, since every Web site has a differentHTML style and uses-different tools, e.g., dynamic HTML, Java,JavaScript, Lotus Notes Scripting, ActiveX, every site map is adramatically different experience to the user. The concept ofdownloading bookmark sets allow the Web site managers to have a commonway to provide the users with the most important site links. Asdiscussed above, the preferred embodiment uses special tags in the fileor a special extension that could be identified by the usage of MIMEtypes as a convenient way to identify a bookmark set. However, thedownload mechanism to move the bookmark set document from the web siteto the client's machine can utilize any known communication protocol.

In the preferred embodiment, the browser participates in the operationof downloading bookmark sets by parsing for the built in MIME typesindicating the bookmark sets extensions, e.g., .bm, .bms, etc. This canbe accomplished by changing the browser itself or adding a plug-in tothe browser. In either case, the bookmark set is made availableimmediately to the user upon entry to a bookmarked site.

As another application of the invention, not only can a bookmark set bedownloaded, it can be preloaded as well. A PC manufacturer can create a“PC Support” bookmark set for a new machine, so that the new user caneasily access that manufacturer's site and related locations such as“Register your PC”, “Problem Solutions” and “Order Accessories” entriesin the bookmark set. That bookmark set could be named “Acme Computer”and is provided the first time the user visits the Acme Computer site.The bookmark set could be updated with as necessary with each visit tothe site.

FIG. 11 is a flow diagram showing a push process originated at a webserver for a plurality of client browsers. In step 451, a bookmark setis created at the server as is described above. In step 453, a set ofbrowsers and their IP addresses are identified which are to receive thebookmark set. Depending on the desires of the system administrator, thebookmark download could be a one time operation or a recurring operationeach time the named bookmark set is updated.

Next, in step 455, the bookmark set is distributed through the networkto the specified set of browsers. In step 457, the distributed bookmarkset is installed in the browser. At this point, the installed bookmarkset is now available for use in the specified browsers as discussedabove.

Contemporaneously with the bookmark set installation, the user isqueried whether he wants automatic update of the bookmark set whenchanges occur at the web site, i.e. does he want to subscribe. If so, instep 459, the browser is listed for automatic update of the bookmark setat the web site. In step 461, a change in the bookmark set is detectedat the web server. The server refers to a list of subscribing browsersand sends the updated bookmark set to the subscribing browsers, step463. The bookmark set is automatically installed in running browsers. Inother browsers, at the next startup, the browser checks for updatedbookmark sets and installs any such bookmark sets. step 465. TheBookmark sets are stored in the Server before downloading.

The server push embodiment is useful for a number of applications. In acompany intranet, it is a useful means for the system administrator toinstall an active bookmark set or a blacklist bookmark set. Setting theoperation as an automatic one means that updates to these bookmark setsare seamlessly distributed to the browsers in the network. It is usefulfor vendor running kiosks at remote locations. The bookmark sets can beupdated automatically as the vendor's web sites change. Alternatively, anew vendor's bookmarks can be installed by the retail chain that ownsthe kiosks. Since the operation can be performed remotely, on a set ofmachines, or on a single machine, remote administration of the browserin the kiosk is possible.

Another application of the present invention is in an environment ofnetwork computers. The client images held at the server can be updatedso that the next time the network computer is started, a new set ofbookmarks is downloaded.

Web Browser Support for Dynamic Update of Bookmarks

As discussed above, the usefulness of bookmarks has also become theirbane. As the number of bookmark entries in a web browser increases, themaintenance task becomes a burden and a manual chore detracting from theWeb interaction experience. The download process described in the aboveembodiment of the invention ameliorates the burden by using the bookmarkset as a means of installing and maintaining a set of bookmarks in asingle operation. However, despite the advantages of the invention, itis expected that many sites will not automatically download bookmarksets.

Furthermore, a user's bookmark set may contain URLs for a variety ofsites. These sites due to their respective popularity or load balancingcharacteristics behave differently from other sites in the bookmark set.Since these user selected bookmark sets are apt to contain bookmarksfrom different vendors, it is not possible to dynamically download thebookmark set as an entity.

It would be advantageous to provide an automated mechanism to update abookmark entry that has become stale due to a change in the name of thesite or a change in the URL due to redirection. A web site that changeslocation normally redirects to the new location, but a bookmark entry inthe user's browser still points to the old address. In this way, manybookmarks subsequently become invalid entries in time.

Yet to update the bookmark, the prior art browser technology requiresthe user to manually add this new address and remove the old bookmark.This is a tedious process and can be confusing to those not familiarwith URL addressing. Even those comfortable with the technology itselfare often frustrated by the length of many URLs.

This invention addresses this problem by providing a method for a website to update the client's bookmarks automatically if the bookmark ispart of a bookmark set and has “dynamic” attributes. This inventionminimizes the length of time necessary to keep an old address and makesthe transition to a new URL address transparent to the user.

The invention introduces the concept of bookmark sets, however, in analternative embodiment, a dynamic bookmark does not have to be part of abookmark set. The bookmark manager must have the ability to recognize adynamic versus static attribute of a bookmark. This is not available inprior art browsers.

The method practiced by this invention allows a web browser to retrieveand store bookmarks by qualifying them as one of two differentattributes: dynamic or static. Static bookmarks never change unless theyare manually updated or deleted. Dynamic bookmarks, on the other hand,are updated dynamically when the page is referenced. While the readermight be tempted to choose a dynamic attribute for all bookmarks, thisis not always a good choice. Everytime the user goes to a popular URLsuch as Yahoo.com, it is not desirable to install the new unsolicitedURLs which have been added to Yahoo.

One special type of dynamic bookmark is the temporary dynamic bookmarkwhich is discussed in the section above as an integral part of thetemporary dynamic bookmark set. Temporary dynamic bookmarks are addedand removed during a visit to a web site. For example, a user justarrived to a www.travel_with_me.com site may have an additional bookmarkset for the site added to his bookmark sets. Some of these bookmarks caninclude important URLs within that site or other related sites. However,as soon as the user leaves the www.travel_with_me.com site, the“temporary” bookmarks disappear from the bookmark set. This “temporary”set of bookmarks is one embodiment of the dynamic bookmarks in thisinvention. Generally, however, the dynamic attributes of bookmarks aredesignated individually by the user.

In the preferred embodiment, at the time of the creation of thebookmark, the user identifies the bookmark as a dynamic or a staticbookmark. If no selection is made, a default attribute as a staticbookmark is stored. By selecting a dynamic bookmark, the user assuresthat this bookmark in his bookmark set is kept current. If the addressor name of the bookmark has changed, the content of the bookmark isautomatically updated.

For example, suppose that a user selected a bookmark for support for theOS/2 Warp operating system. Initially, the URL referenced by thisbookmark is supported by a server in Boca Raton, Fla. Subsequently, thesupport page is relocated to a server in Austin, Tex. If a user of atypical browser made a call using the stored bookmark for the Boca Ratonsite, he would automatically be rerouted by the server network, or lessdesirably, receive notification that the URL was no longer valid. If theuser used a dynamic bookmark of the present invention, when the BocaRaton OS/2 product support bookmark is selected, not only is the browserautomatically routed to the Austin OS/2 support group address, but alsothe browser's bookmark is updated. In the future, the browser will usethe Austin server URL. Thus, the invention will reduce the overall loadon the Internet, speed the connection time for the browser and avoiddead bookmarks.

A web browser can detect a change in either a site's title or URLlocation due to redirection. If either condition exists, the bookmarkentries, e.g., in the active bookmark set, are searched for a match withthe current web site. If the entry is not found in the bookmark set,processing continues as usual.

If a match in either the title or the URL is made between the bookmarkentry and the visited site, the bookmark entry is automatically updated,by either updating the bookmark description or the referencing URL.Updating the date information helps determine the need for furtherupdate.

In one embodiment of the invention, the web browser preferences menu ismodified to contain a “Bookmark Update” selection attribute to enable ordisable the automatic update of bookmark entries. The user can configurethe browser to prevent the automatic update of dynamic bookmarks orbookmark sets, e.g., the loading of temporary dynamic bookmark sets.This way the user will have all static bookmarks, even if dynamicattributes may have been set by a web master.

FIG. 12 shows a typical information message informing the user ofchanges in Web site URLs. In the prior art, the user is required tomanually change the bookmark according to the message. In the preferredembodiment, this invention makes this process transparent to the user.In alternative embodiments, a message from the browser is presented tothe user that the bookmark has been updated.

FIG. 13 shows the architectural relation between the components involvedin an automatic update of a bookmark in a bookmark set. First, theclient 501 sends an HTTP request to old Web address listed in itsbookmark set 502. The server 503 at the old web address receives therequest and responds with an HTTP header and messages containing the newURL for the Web server 505 which now supports the Web page. The bookmarkmanager 507 at the client 501 handles the response. The bookmark manager507 automatically updates the bookmark in the bookmark set 502 byidentifying the old bookmark and updating the bookmark with the new URLinformation. The bookmark manager 507 sends through the web browser anew HTTP request to the new server 505 using the new URL address.

FIG. 14 is a flowchart depicting a process for dynamic update ofbookmarks. In step 521, an HTTP request to fetch a Web page in HTML froma URL. Step 523 tests whether the HTTP request is redirected to anotherURL. If so, step 525 tests whether there is enough information to updatea bookmark. The test in step 525 also determines whether the redirectionis of a type which indicates that the bookmark should be updated. Forexample, many popular sites use many servers to service requests for agiven web page. If a redirection of this type is detected, the bookmarkshould not be updated since support still exists at the main URL for thepage. In step 527, a test is performed to determine whether thepreferences in the browser are set to allow dynamic update of bookmarks.Step 529 tests whether the URL matches a bookmark entry in a bookmarkset. Note that it does not have to be the active bookmark set. Step 531determines whether the matched bookmark has a dynamic attribute. If allof these conditions are met, in step 533, the bookmark entry is updated.In step 535, processing of the HTML in the returned document continuesto include the new HTTP request to the new server address for the Webpage.

Consumer Hotlist Pulldown Bookmarks

The proliferation of commerce on the Web has proceeded explosively, yetsomewhat haphazardly. There are many Web designing tools and many Webdesigning firms, resulting in a bewildering array of user interfaces.However, certain market segments on the Web can now be identified, e.g.,travel, finance, retail, electronic gaming. Each of these marketsegments can be characterized as having a set of common tasks. However,the user's browsing experience varies greatly from site to site. Itwould be preferable if the user was confronted with a consistent userinterface when accessing each web site that caters to a specific marketsegment.

On many Web sites, an attempt has been made to provide a somewhatrudimentary common interface with features such as “search”,“contact-us”, etc. The dialog to access these features is found usuallyat the bottom or top of the Web page. However, the code to manage thedialog is embedded code in the web page. The problem is aggravated whencommon tasks such as “purchase”, “order” and others are implementedusing custom dialogs. Each site decides to implement the custom dialogin unique and often obtuse fashions, bewildering the consumer with aplethora of different user interfaces.

In this embodiment of the invention, a web user to utilizes a bookmarkset of provided bookmarks for a set of actions, preferably a set ofactions common to a particular market segment. The provided bookmark setis used by the bookmark set manager to provide a user interface muchlike pull down menus to select actions for the web site. Each web sitehas similar sets of bookmarks as do other sites which offer similarservices. The bookmark sets which contain pull down menu items arecalled “consumer hot lists”. In the preferred embodiment, the consumerhot list provides a polymorphic bookmark set, where the name of thebookmark is fixed, but the URL address is dynamic in nature.

A consumer hot list is composed of a consumer “request”, a text stringfor display in the user interface which indicates what will happen ifthe request is selected and a web “action”, a URL to another web page.Examples of consumer requests are generic actions such as “purchase”,“feedback”, “support”, and so forth. As a result of selection of therequest, the applicable web action is performed by the web server, i.e.typically redirection to another web document. This consumer hot list isa bookmark set which is downloaded to the browser with the requested webpage.

The user experienced with downloaded bookmark sets will quickly gain abasic understanding of the operation of the consumer hot lists. In thepreferred embodiment, a standard bookmark set of requests is provided tothe browser for each Web page in the same industry. Thus, bookmark setscan be provided by industries such as Clothing, Manufacturing, Software,Banking, Gaming and Education. Further granularity within an industry isallowed.

Typically, a Web server associated with the original Web page serves theWeb page which supports a respective action in the consumer hot list.The server creates a named consumer hot list and stores the documentusing a particular MIME type, e.g., chl/x-consumer-host-list. The MIMEtype for a temporary dynamic bookmark set could also be used. When thebrowser retrieves the consumer hot list MIME type, it creates a separatepull down window, listing all the requests supported by this Web pageapplication.

Visiting a different site automatically updates the consumer hot listrequest and action items.

Some examples of consumer hot lists are given below. The reader willunderstand that the hot lists below are illustrative and that similarand more extensive lists can be developed for these and otherindustries.

In the Banking industry, the bookmarks of the consumer hot list pulldownare:

Savings

Checking

Balance Inquiry

Bill Payment

The associated actions are the URLs for Web pages which provide therespective consumer action.

In the Gaming industry, the bookmarks of the consumer hot list pulldownare:

Start Came

Look for Players

Game Options

Levels

In the Retail industry, the bookmarks of the consumer hot list pulldownare:

Purchase

On-Sale Today

Review Order

Review Shopping Cart

Consumer Address

Web browsers are becoming the primary user interface for a personalcomputer. As Web browsers also provide the primary interfaces forspecific market segments, the consumer hot list feature of the presentinvention makes it possible to provide a consistent interface for eachmarket segment.

The creation of the consumer hot list starts by associating particularrequests, common to a market segment, to a custom action or task. Forexample, the request to specify a Credit Card Purchase is associatedwith a Web page, which might supply a Credit Card Information form. Inthe preferred embodiment, the transmission of credit card informationand the like is always encrypted. Since the consumer can rely on thisfact, the common association of request and encryption eases theconsumer fear of sending personal or accounting information in theclear.

An association table is created and embedded in a Web page that isdownloaded to the browser when visiting the web site. The receivingbrowser accepts the consumer hot list association table which ispreferrably identified via HTML tags and modifies any existing consumerhot list pulldown menu to reflect the current settings. Anotherembodiment of the invention is to make a consumer hot list a temporarydynamic bookmark set which is only active while the user is at the website.

An example of an association table with a few examples of associatedactions is given below:

Association Table

<Consumer-Public-Domain>

<CNSMR-Keyword> Purchase</CNSMR-Kbyword>

<CNSMR-Action> Form-Purchase</CNSMR-Action>

<CNSMR-Keyword> On-Sale-Today</CNSMR-Kbyword>

<CSMR-Action>htt://Sale-Today.html</CNSMR-Action>

<CNSMR-Keyword>Review-Order<CNSMR-Keyword>

<CNSMR-Action>http://ReView-Order.html</CNSMR-Action>

The setting of the consumer hot list parameters can remain active untilreset by a subsequent visit to a different web site for the sameindustry. Alternatively, the hot list parameters may be temporarydynamic ones which are removed from the browser at the conclusion of theweb site session.

The association table for the current request parameter should be thesame, i.e. same keyword for specific industries. For example, alllending libraries would have common requests such as: checkout, reserve,return, extend loan, request library card and so forth. The actions foreach request are implemented by each institution using their own webpages and URLs.

FIG. 15 shows how a consumer hot list 551 can be presented on a retailsite like www.sears.com. Notice that the bookmark set 551 includesrequest items such as Purchase 552, On-Sale Today 553, Review Order 554,Review Shopping Cart 555 and Consumer Address 556. The selection of anyof these bookmarks would result in the retrieval of a web page whichwould provide the listed action.

FIG. 16 is a flowchart of the consumer hot list process. In step 601,the browser has requested a web page to be fetched from a web server. Instep 603, the browser begins to parse the HTML and determines whetherthere is a consumer hot list tag in the page. If so, the consumer hotlist is downloaded and set as the active bookmark set, step 605. Anexisting bookmark set may be updated in this step. In step 607, apulldown is presented to the user containing the consumer hot listbookmarks. In step 609, the remaining HTML in the page is processed bythe browser for presentation to the user.

In step 611, the browser detects that the user has selected a bookmarkin the consumer hot list. In response the browser retrieves a web pageat the URL of the selected item, step 613. In step 615, the browserprocesses the page as dictated by the HTML.

The embodiments described above have shown the utility of the bookmarkset of the present invention. By handling a set of bookmarks as anentity rather than on a one by one basis as done in the prior art, avariety of functions can be accomplished through the use of bookmarks.The bookmark sets can be used to control user access to the web.Attributes of the bookmark entries can be set as a group to provideautomatic update of bookmarks, or other functions for the entire set.

Although the discussion above has focused on the use of HTTP and HTML asthe most popular protocols in current use in the Web. The invention isnot limited to these protocols. Bookmarks can be created for sites usingthe FTP and gopher protocols. Download of bookmark sets is possibleusing these protocols as well.
